Water’s heat of vaporization is 2,257 joules/gram. how much energy is released when 11.2 grams of water vapor condenses into liquid?

25278.4 j

Explanation:

Given data:

Heat of vaporization of water = 2257 j/g

Energy released by converting 11.2 g water to liquid = ?

Solution:

The heat of vaporization of water is = 2257 j/g

It means one gram of water when converted into vapors 2257 j heat is involved.

For 11.2 grams of water when  converted into liquid energy released would be:

11.2 g× 2257 j/g

25278.4 j
